APPARATUS FOR PRINTING FRONI PHOTOGRAPHIC NEGATIVES.

SPECIFICATION forming part of' Letters Patent No. y7:`4,090, dated July 5, 1904,

Application filed March 28, 1904. Serial No. 200,465. (No model.)

T 0 all whom, it may concern:

Be it known that I, FREDERICK C. IVI-urn, a citizen of the United States, and a resident of Chicago, in the county of Cook and State of Illinois, have invented certain new and useful Improvements in Apparatus for Printing from Photographic Negatives, of which the following, when taken in connection with the drawings accompanying and forming a part hereof, is a full and complete description, sufiieient to enable those skilled in the art to which it pertains to understand, make, and use the same.

This invention relates to mechanism by means of which a photographic negative, particularly when such negative is on a film, as it is termed in the art, can be readily and easily handled in the printing therefrom of photographic positives; and, further, it relates to mechanism by means of which a photographic positive may be printed from a negative film of a given size on a sheet of paper cut to a larger size than is such film; and, further, it relates to mechanism by means of which a border of a determined width may be placed on the positive print in proper relation to the view or picture printed thereon from the negative used.

The object of this invention is to obtain an apparatus for the purpose set forth which may be made and used by persons reasonably skilled in the art of photography.

YA further object of the invention is to obtain an apparatus for the purpose set forth which can be economically constructed by the person desiring to use the same, as well as by manufacturers thereof for sale, which is simple, durable, and not liable to be broken or otherwise injured and by means of which the party using-the same can readily obtain prints, from film-negatives particularly, which will be neat and clean in appearance.

An apparatus embodying this invention is illustrated in the drawings accompanying and forming a part of this specification, hereinafter referred to, and in which- Figure 1 is a top plan view of a templet used in'making the print-controlling portions of the apparatus embodyingv this invention with a glass plate thereon. Fig. 2 is a crosssection of the templet illustrated in Fig. I on line Q Q thereof viewed in the direction indicated by the arrows with the glass plate which is shown in Fig. I removed. Fig. 8 is a top plan view of a gage for printing a border' from a negative formed by such gage, such gage being made on the templet illustrated in Figs. l and 2. Fig. 4 is a cross-section of the gage illustrated in Fig. 3 on line 4 4 of such Fig. 3 viewed in the direction indicated b v the arrows. Fig. 5 is a top plan view of a combined film-holder and gage made on the templet illustrated in Figs. yl and 2. Fig. 6 is a cross-section of the combined filmholder and gage illustrated in Fig. 5 on lines 6 6 of' such Fig. 5 viewed in the direction indicated by the arrows. Fig. 7 is a top plan View of an ordinary printing-frame used by me as an element in the operation of the apparatus embodying this invention. Fig. 8 is a side elevation of the back of the printingframe which is illustrated in Fig. 7; and Fig. 9 is a view of a print obtained from a negative film by means of the apparatus embodying this invention, showing a border obtained from the combined gage and negative illustrated in Figs. 3 and 4.

A reference-letter applied to designate a given partis used to indicate such part wherever the same appears throughout the several figures of the drawings.

A is a templet and comprises body part a, rail a', extending along two of the sides of body a, and a locking device or part, which preferably consists of the wedges lf fr, firmly secured to the body part a, and the movable wedges a7 a3, engaging with the wedges f a2, respectively, and the sheet of glass B, Fig. l, which is secured in place thereby on templet A with its edges which are adjacent to the rail a closely in contact therewith.

C C, C' C, and D I) are respectively lines or marks on the body a of templet A. The

several squares obtained by the intersection of the lines C C are of a size to correspond with one size of photographic films or plates, and the squares obtained by the intersection ofA the lines C C are of size to correspond with a different size of photographic films or As many of such lines C C C C may plates.

IOO

be placed on the templet as desired in order to obtain additional squares for differentsize films. The square obtained by the lines D D is used for making' the combined holderl and gage illustrated in Figs. and 6 and hereinafter described when it is desired to obtain, in a print made from negatives by the use of this apparatus, a view or picture not extending closely to the border obtained by the use of the gage illustrated in Figs. 3 and 4.

E, Figs. 3 Vand 4, is a combined negative and gage and consists of glass plate e, cover e e2 e3 to such glass plate, and projecting' lugs e5 e5 on the side of the glass opposite to the cover e/ e2 @3.

c* is an opening between the part e' of' the cover of plate e and part e2 e3 of such cover.

To make the combined gage and negative E, a piece of clear glass, as B, Fig. 1, is placed in templet A and secured firmly in position, as by wedges a2 and a3. A sheet of gummed paper of a color not permitting actinic rays to pass therethrough, as, say, black, of a size as large or larger than the portion of the film or negative which is to be printed by the use thereof is then made to adhere to the sheet of clear glass, the position of such gummed paper on the clear glass being determined by the lines C C or C C' or other like lines on templet A. In Figs. 3 and 4 the gummed paper e is of the proper size to be used in making a print of the size laid out by lines I A larger piece of gummed C C of Fig. 1.

paper e would be vused to make .a 'printof about the size of ythe square formed by the v lines C 1C of such Fig. 1. In practice I pr-efer to make the sheet Aof gummed paper e before itis gummed to the glass B larger than it is to ultimately be and to secure such larger sheet on the glass to overlap the square made by the lines, as, say, C C', and after the same is firmly attached to the glass to-cut it down by means of' a knife and a straightedge to the size of the square made by ysuch lines, as I thus insure not only the exact position to the part e on the glass B, but also the exact lsize thereof, so that the same will properly register with the gage and holder illustrated 1in Figs. y and 6 and hereinafter described. After the gummed piece e is secured firmly in position and made of proper size the vstrips e3 @3 (indicated by dotted lines in Fig.. 3) of gummed paper may be successively attached to the glass B in position .to leavethe clear-glass opening e4, and then the part of the cover e2 maybe gummed in place. Strips e3 e3 may be gummed in place at any suitable distance from the Vseveral edges of the part e and parallel thereto, the width of the clearglass opening corresponding with the desired width of the border. (See Fig. 9, border 'G G Gr2 are marks made, respectively, on the templet A, the combined gage and negative E, and the printing-frame X to indicate the relative position which such parts should at all times have with each other in the making and use ofthe apparatus. f

The lugs e5 e5 are placed on the gage E `so that when such gage is in the printing-frame the outer edges of such lugs will be in contact or close to contact With the respective edges of the front opening of the printing-frame, such edges of the printing-frame being indicated by broken lines X X/ in Fig. 7, to hold the edges of the gage adjacent to the mark G2 on vthe printing-frame in close contact with such edges.

H is a combined film-holder and gage, Figs. 5 and 6, made on the templetAin the following manner: A sheet of clear glass is placed in position on templet A in the same manner as is done to make the combined negative andA gage E. Assuming that the combined filmholder and gage H is to be used in conjunction with the combined negative and gage E for the printing of a photographic positive, a gummed-paper covering is placed on the sheet of glass, with an aperture therein corresponding in position and size with the portion c of the combined negative and gage E or corresponding in position :and size with the square formed by the lines D D in Fig. 1. When the aperture in the gummed-paper covering of the combined holder, and gage H is made of the same size as the part c' of the cover of gummed paper on combined negative and gage E, th-e picture printed from a negative when this apparatus is used will extend to the border obtained, as is illustrated in Fig. 9, and when such aperture is of the size to correspond to the square made by the lines D D in Fig. 1 the picture will not extend to the border F F, the space between such picture and border being equal to the space between the square made by the -lines D D and the square made `by the lines C C in Fig. 1.

In making the combined holder and gage H, I prefer to successively attach strips of gummed paper, 1as L 7L' h2 if, to the glass, and after such strips have all been gummed in place, with the inner edges thereof corresponding with the lines C C, the flaps lf, of paper or thinI cardboard, are attached in place, as by gumming them. The inner edges of the fiaps la* engage with the ledges `of 'the filmnegative from which the print is to be obtained, such edges coming underneath the edgesof the flaps, as is indicated by the broken lines I I in Fig. 5. Broken ylines I I indicate the negative, either on film or glass, which may be used with the combined negative and gage E andthe combined holder and gage H to obtain a picture-as, say, the photographic print illustrated in Fig. 9.

lf if are lugs on the combined holder and gage H, corresponding in position and function with the lugs e5 I5-on combined negative and gage E.

J, Figs. 7 and 8, is the back to the printingframe X. This back is composed of two IOO parts jj", joined bythe hinges f2 in the ordinary way and provided with the ordinary springs K K.

L L are projecting' lugs, usually of' metal, on frameX, with which the springs K K are broug'ht into engagement to hold the paper on which the photographic print is to be made in close contact with the negative used.

W' here the combined holder and gage H is used for holding a photographie film, the thickness of the covering of such combined holder and gagew-that is, the thickness of the several strips 7L It /f /L3-tends to hold the film oii' from contact with the photographic-printing paper, and in order to force such film down to close contact with the paper or to force the printing-paper closely against the negative film I place pieces M M, Fig. 8, on the under side of the parts j j of the back J. Such pieces may consist of cardboard of substantially the same thickness as the combined thickness of' the cover and iiaps ofthe combined holder and gage H.

' The manner ofl the operation of this apparatus is as follows: The combined neg'ative and gage E is placed in the printing-frame X with the covered side thereofl toward the back of the printing-frame. A sheet of photographie-printing paper isl placed against such negative and gage with two of its sides in contact with the sides of' the printing-frame corresponding with the rails a a of' templet A and the back J is placed in the printing-frame and secured against the paper in tne usual way. Such paper is then exposed to a suitable light for a proper length of time. The paper and the combined negative and gage are then removed from the printing-frame, and the combined holder and gage H, with a photographic film therein, is put into the printing-frame with such film on the side of the combined holder and gage which is adjacent to the back J. The printing-paper which has been exposed on the combined negative and gage E is then placed in position in the printing-frame on the combined holder and gage and on the negative film held therein with the two of its sides which were in Contact with the sides of' the printing-f`rame when such printing-paper was placed over the combined neg'ative and gage again broughtv into contact with such sides, and thereby such paper registers with the holder in gage H and with the printing-frame in the same manner as when placed in such printing-frame with the combined negative and gag'e E. The back J is then placed in the printing-frame and secured in position to hold the printing-paper against the negative iilm. Pieces M M press such printing-paper firmly against the film. The printing-paper is then again suitably exposed to a light. The paper is then taken from the printing-frame and developed in the ordinary way.
